SFO/EWR are the junior bases for new hires. Depending on the vacancy bids there may be other options but at a minimum SFO and EWR will be on the slate. If you don’t get EWR b/c you choose your preferred airframe in SFO and it’s not open in EWR, it will be open on the next vacancy bid almost for certain and certainly by the time you are done with OE. It may take a couple of months to activate your award but you will be in EWR in less than 6 months.
